Deposit & blocked account 3 min read · published September 11, 2025
As a tenant in Norway it can be unclear who must pay if you lose a key and the landlord demands deductions from the deposit. This guide explains what typically applies, which costs may be reasonable, and how you document the situation to get your deposit back or dispute a deduction. The text discusses relevant rules in the Tenancy Act[1] and how you can complain to the Tenancy Disputes Board (HTU)[2] or bring the case to the conciliation board if necessary. The goal is to give practical steps and examples so that you as a tenant understand rights and obligations in housing situations in Norway. Read on for concrete advice about cost allocation, documentation requirements and deadlines for objections.

Why can the landlord demand payment?

The landlord may demand payment for costs that arise from the tenancy agreement and reasonable restorations after the tenancy ends. The Tenancy Act regulates which deductions can be made from the deposit, for example in case of damage or failure to return keys.[1] A deduction must be proportionate to the actual cost and not punitive. If the landlord requests an amount you consider unreasonable, you should ask for an itemized bill and documentation.

Request receipts and an itemized bill before accepting a deposit deduction.

Common costs when a key is lost

  • Changing the lock and a new key (keys) — cost for a new cylinder and keys.
  • Deposit deduction (deposit) — if the landlord documents costs resulting from failure to return keys.
  • Locksmith labor (repair) — hourly cost to install a new lock or change a cylinder.
  • Cost for extra keys or changing a master key (deposit) — especially for access to shared systems or multiple locks.

The landlord must be able to document all costs with receipts or invoices. If the amount is set without documentation you can request an explanation and refuse unreasonable claims. If you cannot agree, the matter can be taken to the Tenancy Disputes Board (HTU) or the conciliation board for resolution.[2]

Detailed documentation increases the chance of success in a dispute.

How to calculate a reasonable cost

A reasonable cost normally corresponds to expenses necessary to restore the leased property or secure the building. The landlord cannot claim amounts that act as penalties. Request an itemized invoice showing materials and labor time. Compare with local locksmith quotes if the bill seems high.

Do not pay a claim without documentation if you believe it is unreasonable.
